Depending on the pore size of the used filters (membranes), contaminants with different sizes can be removed and a better purification can be achieved while decreasing the pore size; thus, the available methods are: (1) microfiltration (pore size about 0.1 μm), which removes bacteria and suspended solids in the water; (2) ultrafiltration (pore size about …

SMALL-SCALE PURIFICATION OF WATER organisms embedded in solid particles. Chlorine enters almost instanta- neously into chemical combination with organic matter in water, and in such combined form it is of no use for disinfection. Sufficient chlorine must therefore be added to satisfy the "chlorine demand" of water in addition to the …

In rapidly growing urban areas, such as Tijuana, Mexico, the presence of urban green spaces (UGSs) can help stem soil erosion, improve infiltration, slow runoff, decrease flooding, reduce air pollution, and mitigate climate change. In many water-scarce parts of the world, where centralized wastewater treatment is not accessible or …
Student teams design and then create small-size models of working filter systems to simulate multi-stage wastewater treatment plants. Drawing from assorted provided materials (gravel, pebbles, sand, activated charcoal, algae, coffee filters, cloth) and staying within a (hypothetical) budget, teams create filter systems within 2-liter …
